Economic market instruments and sustainable urban water use
Water is an economic good and as such has as a value to a spectrum of users, who are willing to pay for it. Consumers will use water until the marginal costs exceed the marginal benefits from use of an additional cubic meter of water. Similarly, producers will supply water until the marginal costs exceed the marginal return of an additional cubic meter of water supplied. This article surveys the ...

Estimated costs of implementation of membrane processes for on-site greywater recycling
Greywater reuse inside buildings is a possible way to preserve water resources and face up to water scarcity. This study is focused on a technical-economic analysis of greywater treatment by a direct nanofiltration (NF) process or by a submerged membrane bioreactor (SMBR) for on-site recycling. The aim of this paper is to analyse the cost of recycled water for two different configurations (50 and ...

The impact of diurnal water use patterns, demand management and rainwater tanks on water supply network design
The traditional use of long-term average consumption records and “peak factors” to determine water network design criteria does not account for allotment-scale diurnal water use patterns which impact upon the dynamics of water distribution systems. The diversity of allotment-scale diurnal water use patterns directly impacts on network dynamics. Demand management and rainwater tanks are likely to ...

Ozone as a Disinfecting Agent in The Reuse Of Wastewater
More and more countries are taking measures to reuse wastewater. This has been prompted by the ever decreasing availability of good quality raw water and the increasing cost of producing potable water. Disinfection is a major treatment step in the direct reuse of reclaimed wastewater to ensure environmental and public health protection. “Disinfection is the destruction, inactivation or removal ...

Waste water treatment costs reduced by 50% with rotary vacuum precoat filter - Case Study
Problem: The solids separation system at Lindc's waste water treatment facility had high operating, maintenance and sludge disposal costs. High operating costs were caused by the large pumps and special treatment chemical required to operate the filter, and frequent cleaning, repair and replacement of filter elements resulted in high maintenance costs. Union Carbide Corporation's Linde Division ...

Falling Oil Price Forces Operators to Find Cost Savings in Water Management
When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...
